Abstract

Apparatus for producing iron by reduction of iron ore, characterized by the combination of a reduction furnace adapted to receive iron ore and reducing agent and having closed discharge means for discharging successive amounts of material comprising reduced ore, a vessel of rotary cooling having means for cooling the outside thereof, conduit means extending from the furnace discharge means to the feed end of the cooling vessel and arranged in closing relation therewith, to conduct quantities successive of the reduced mineral material to the vessel, the vessel communicating with the kiln discharge means to provide non-oxidizing atmosphere in the vessel, a quench tank for containing quench liquid and discharge conduit means closed with respect to the end of the vessel. discharge from the cooling vessel and that extend inside the shut-off tank below of the level of liquid contained therein, for the discharge of successive quantities of reduced ore in the quench liquid after passing through the cooling vessel.
